What’s the coolest thing you’ve ever found (and kept)?

Bud was nearing the end of nursing school as we neared the end of our funds. He was piddling around with his camera and opened a box of film that had been sitting on the shelf awhile. Disappointed to find it held no film, he assumed it was a rolled up instruction manual. Frustrated, he intended to trash it but unrolled it first. Stunned, he found it was a roll of hundred dollar bills: three thousand dollars in total! His hands were shaking when he came rushing in to tell me of his incredible find. He had no idea how long that box had been waiting on the shelf. It couldn’t have come at a more fortuitous time.
